Functionality

Analogous to the spin operator and the Screw modifier. It takes a profile shape as input in the form of vertices and edges and produces vertices and faces based on a rotation axis, angle, center, delta and step count. Internally the node is powered by the bmesh.spin operator.

Inputs

It’s vectorized, meaning it accepts nested and multiple inputs and produces multiple sets of output

Parameters

All Vector parameters (except axis) default to (0,0,0) if no input is given.

Param	Type	Description
cent	Vector	central coordinate around which to pivot
axis	Vector	axis around which to rotate around the pivot, default (0, 0, 1)
dvec	Vector	is used to push the center Vector by a Vector quantity per step
Degrees	Scalar, Float	angle of the total rotation. Default 360.0
Steps	Scalar, Int	number of rotation steps. Default 20
Merge	Bool, toggle	removes double vertices if the geometry can be merged, usually used to prevent doubles of first profile and last profile copy. Default off.

Outputs

Vertices and Poly. Verts and Polys will be generated. The bmesh.spin operator doesn’t consider the ordering of the Vertex and Face indices that it outputs. This might make additional processing complicated, use IndexViewer to better understand the generated geometry. Faces will however have consistent Normals.

Example of usage

• Generator->Generatots Extended-> Spiral
